Thymidine Kinase 2 Deficiency (TK2d)

LGMD and MITO Depletion Panel
This program offers no-cost access to a 55-gene panel for patients with symptoms that may indicate TK2 deficiency (TK2d), mitochondrial DNA depletion syndromes (MDS), or LGMD-like presentations with unclear etiology. Because TK2d can clinically overlap with both MDS and LGMD, this broader panel supports efficient evaluation across these disorders. Testing is available at no cost for eligible U.S. patients.
